A Guide to Security Bollards

Bollards can be an extremely effective form of physical security for a business. In order to make them as robust and efficient as possible, they need to be fit for purpose and placed correctly around the site.

When conducting a site survey, it is imperative that the entire surroundings are taken into account, especially if the site has vehicle access, as you need a thorough understanding of what the security risks are and how bollards can help potentially reduce this threat. Security bollards can be an effective solution to some security risks including speeding drivers and vehicle attacks. Here is our guide to security bollards.

Why should bollards be used?

There are many reasons why bollards should be used on some sites to boost their overall physical security. Here are just a few of the reasons why businesses can benefit from installing bollards:

•    They deny entry to vehicles into certain areas without the need to restrict pedestrian entry or install a barrier or gate
•    They are a great safety measure to protect pedestrians from vehicles
•    Rising bollards help restrict vehicular entry to areas during certain hours rather than it being a permanent fixture. This provides businesses with a lot of flexibility over their security measures
•    They prevent vehicles from getting too close to or damaging property or buildings
•    The more robust Hostile Vehicle Mitigation (HVM) bollards are specifically designed to protect sites from terrorist vehicle attacks
•    They can blend in well with their surroundings when designed and implemented correctly and feel less intrusive than some other forms of physical security

Crash rated and non-crash rated bollards

Security bollards tend to be split into two broad categories: crash rated and non-crash rated. Crash rated bollards have been put through rigorous testing by government-approved bodies and determine the level of resistance.

Non-crash rated bollards are still robust and a great form of protection, however they are not designed to be completely resistant to vehicle crashes. As their resistance power is not as robustly tested as crash rated bollards, they are best suited for lower-risk sites.

Anti Terrorist Bollards

Our X Pass and Ranch range are all crash tested and certified by an accredited laboratory according to the latest international standards. Their hydraulic power packs are independent to each other, meaning that if one fails, the other bollards will remain unaffected. They are fitted with anti-tampering kits as standard and are the perfect choice for protecting more sensitive sites.

Automatic Bollards

Automatic bollards use a simple yet effective electrohydraulic mechanism that ensures a smooth and efficient movement of the bollard.  They are great for areas where you will sometimes need to allow access for vehicles but not all the time. The automatic bollards give a business complete flexibility over the timings.

The GA7276H Automation Bollard from Gateway Automation is controlled by a CDS dedicated control unit, which is capable of controlling up to four bollards simultaneously. For added safety, they are fitted with obstacle detection and a crown of LED lights is mounted on top of the cylinder along with a built-in acoustic warning signal.

Pedestrian Flow

A thorough understanding of pedestrian movement through the site is vital for arranging bollards. Sites must ensure that pedestrian movement is still comfortable and convenient. They should not be placed where pedestrian conflicts occur, such as areas of limited visibility, and the height of bollards need to be considered. This is especially important during winter months when lighting is not as great.

Bollard Spacing

Spacing between bollards is also an important consideration that businesses need to look at. It is essential that the gaps are not big enough to allow vehicle access but are large enough for disabled people to access. There must always be enough space for easy wheelchair action. An absolute minimum is 1000mm.

When planning the bollards, the spacing between each one should be equal wherever possible. They should also be at least 500mm away from the edge of roads.

It is also important that no chains or rope are used between barriers. Doing so can cause hazards for blind or partially sighted people and can put them at risk.

Which bollard is best?

When choosing which bollards are best, there are no strict guidelines. Choosing the best bollard is completely dependent on the site in question and what their requirements are. From knowing their needs and their vulnerabilities,  an appropriate bollard can be chosen and installed. It is important you determine where you are planning on placing the bollards and then decide which type you go for.
